CBSE 12th

Hi John,
After 12th, you have a lot of options. The important point is what you want to do, where does your interest lie. Some of the popular options are:
B.Sc (G): You can pursue a general Bachelors in sciences course and later on go for M.Sc or MBA.
B.Tech: Engineering is still one of the best options, as it opens door to many career avenues later on.
B.Arch: If yo are interested in architecture, you can go for this course.
BA: Many students go for BA, as they have the advantage of pursuing all the major subjects in arts stream.
BA physics (Hons): This is still one of the best course in Science specialization at Bachelor's level. Later on, you can go for higher studies.
B.A. Eco (H): If you are keen in getting economics, this is the course for you. After completing this course, you can pursue the master courses from Delhi School of Economics, which has produced some of the well-known economists and a former Prime Minister too.

Both the courses are entirely different and need different eligibility criteria. If you already are a graduate then go for only LLB or integrated LLB-LLM. In case you just did your 12th, then definitely you should go for BA-LLB.
Doing an integrated BA-LLB is going to save your fee, life's one precious year as well as the test of clearing a test after graduation where the level of the test becomes difficult.
There are many good universities like National Law School, Lovely Professional University, Panjab University, Chandigarh University, etc., that are offering integrated BA-LLB. These institutes have varying eligibility criteria. Some offer admission just on the basis of CLAT/LSAT, some offer admission on CLAT/ LSAT/ their own test, some offer admission just on the basis of marks in previous qualifying exam and some offer admission on the basis of CLAT/ LSAT/ their own test/ marks in previous qualifying exams.
Check the websites of these universities for more details.
Good luck.
